Hi Magenta. This issue has come up before. Unfortunately I have been unable to recreate the problem my end, and as it's a crash with no error message it's very difficult to determine what the problem is, but I am investigating.
It is possible to make the game playable again if you delete save_data.dat from: c: Users > [username] > AppData > Local > Deeper_Into_Space. Sadly that will reset your progress I'm afraid. I'm sorry there is not a more agreeable solution, but as I said, I am looking into it.
<update>
Hold up. If you haven't deleted your save_data.dat just yet, hold off from doing it. I'm pretty sure I have (finally) found the issue and fixed it. A patch should un-brick the game, and while you will lose the current run, all your unlocks and stats will remain. I'm going to do some more testing to make sure and hope to get an update out tomorrow.
